In this hint, I will briefly explain what’re the differences between Boundaries Vs Thresholds Vs Limits in SharePoint.
It’s also recommended to read SharePoint 2019 Limitations.
Boundaries Vs Thresholds Vs Limits
Boundaries: Static limits that cannot be exceeded by design.
An example of a boundary is the 2 GB document size limit; you cannot configure SharePoint Server 2013 to store documents that are larger than 2 GB. This is a built-in absolute value, and cannot be exceeded by design.
Thresholds: Configurable limits that can be exceeded to accommodate specific requirements,
A good example is the document size limit. By default, the default document size threshold is set to 50MB but can be changed to support the maximum boundary of 2GB.
Supported limits: Configurable limits that have been set by default to a tested value.
An example of a supported limit is the number of site collections per farm.
